On: Ask HN: Are mobile phones on a plane taking off or landing really dangerous?

The 767 was first built in 1981, long before everyone in the passenger cabin was emitting microwave-class RF radiation.

The plane itself serves as a very large shield to outside radiation, but I'm guessing the internal wiring is not RF-shielded because of weight concerns. Wonder how much it costs to rewire a 30 year-old plane.

It cost $368 Million when the FAA forced operators to replace Mylar insulation (cause of at least two accidents):

According to this very interesting IEEE article, it costs anywhere from $1-5M per airplane, which doesn't include lost business cost:
